If you own a Lenovo laptop, you better go check your power cord.

The computer brand has issued a recall for hundreds of thousands of AC power cords over fire and burn hazards, according to a notice from the U.S. Consumer Product Safety Commission. The recall affects 500,000 power cords in the U.S. and 44,000 in Canada.

According to the notice, the affected power cords can potentially overheat, causing a fire and/or burns. Fortunately, no injuries have been reported, but Lenovo has received 15 reports from outside the U.S. of incidents involving "overheating, sparking, melting, and burning," the agency said.

The problem affects Lenovo's LS-15 AC power cord manufactured from February 2011 to December 2011.

The power cords were distributed with IdeaPad brand B-, G-, S-, U-, V-, and Z-series laptops as well as Lenovo brand B-, G-, and V-series laptops. The recalled power cords are black in color and are marked with "LS-15" on the AC adapter end. You'll also see the manufacture date in the format REV: 00 YYMM on a label attached to the cord.

Laptops with the affected power cords were sold at computer electronics stores, authorized dealers, and on Lenovo's website from Feb. 2011 until June 2012 for between $350 and $1,500.

"Consumers should immediately unplug and stop using the recalled power cords and contact Lenovo for a free replacement," the Consumer Product Safety Commission said.

Affected individuals can contact Lenovo at (800) 426-7378 from 9 a.m. to 5 p.m. Eastern Monday through Friday.
